Narrabri Whitehaven Oxidation

Objective

The fly ash was injected using nitrogen to prevent oxygen ingress into the inertised coal mine.

Scope

Design, delivery, and Project Management of fly ash injection UG to reduce ventilation movement through the LW109 goaf and adjacent roadways in two locations.

Result

GEM assisted ventilation controls for goaf oxidation successfully by helping oxygen levels downstream within the goaf reduced after fly ash injection.
